APPENDICES
A - Recommended gauge for checking squareness of thread
to face of nut
B - Chemical composition of steel bolts and screws
C - Chemical composition of steel nuts
D - Testing of mechanical properties of steel bolts and
screws
E - Testing of mechanical properties of steel nuts
F - Examples of the marking of bolts, screws and nuts
G - Association of bolt and screw lengths and diameters
H - Basis for the derivation of tolerances
J - BSI policy statement on screw threads and the metric
system
K - Manufacturers' recommended range of sizes
General dimensions and tolerances of bolts, screws and nuts with ISO metric threads to BS 3643, in diameters of 1.6 mm to 68 mm (for the convenience of users requiring larger sizes, further information in relation to the derivation of tolerances is provided in an appendix). Mechanical properties are given in respect of carbon and alloy steel bolts, screws and nuts, but the dimensional requirements apply also to non-ferrous and stainless steel bolts, screws and nuts.
